Nice, nice! Cute anime style and a decent story, an addictive gameplay and varied character with their own powers, good!
I won't complain about the art, you just need to keep drawing and try harder :)
For gameplay, some character are just way too overpowered, but its fine since they have low health, like flower. Come to talk about her, why her name is "flower"? its doesn't sound like a proper name.
Rick is simply way too overpowered! super high health with powerful ability, while Bill and Blossom is too weak!
Bill have nice S5 power, but it doesn't really work well. Plus, he suppose to be a gamer, but his appearance doesn't really show that (well, maybe he was cosplaying)
For Blossom, she suppose to be strong in the story, but her health is the lowest and her attack is the same as Bill, she suppose to learn Karate isn't it? And her S5 is the worst, high movement speed but only one power increase? that doesn't work.
Good game anyway, keep trying and good luck!
